9fe8eccad4 HID: sensor-hub: Fixup for Lenovo ThinkPad Helix 2 sensor hub report
There is an error in the report descriptor of the Thinkpad Helix 2 where
logical minimum value (557376) is greater than logical maximum (491200)
for all of the magnetic flux axis data fields. This error results in a
report descriptor parsing failure that causes the sensors attached to the
hub not to be detected.

dmesg excerpt:
[   19.866905] drivers/hid/hid-core.c: logical range invalid 0x88140 0x77ec0
[   19.866914] hid-sensor-hub 0018:2047:0855.0007: item 0 1 0 8 parsing failed
[   19.866926] hid-sensor-hub 0018:2047:0855.0007: parse failed
[   19.866933] hid-sensor-hub: probe of 0018:2047:0855.0007 failed with error -22

Add a report fixup to change magnetic flux logical minimums to -557376
for the parsing to succeed and the sensors to get detected.
After applying the fix the sensors get detected, with corresponding drivers
(hid-accel-3d,hid-gyro-3d,etc) loaded, and its possible to read their values.

52a45f38ca mac80211: avoid VHT usage with no 80MHz chans allowed
Currently if 80MHz channels are not allowed for use, the VHT IE is not

AP is configured with the wrong regulatory and supports VHT even where
prohibited or in TDLS scenarios.
Mark the ifmgd with the DISABLE_VHT flag for the misbehaving-AP case, and
unset VHT support from the peer-station entry for the TDLS case.

22f66895e6 mac80211: protect non-HT BSS when HT TDLS traffic exists
HT TDLS traffic should be protected in a non-HT BSS to avoid
collisions. Therefore, when TDLS peers join/leave, check if
protection is (now) needed and set the ht_operation_mode of
the virtual interface according to the HT capabilities of the
TDLS peer(s).

This works because a non-HT BSS connection never sets (or
otherwise uses) the ht_operation_mode; it just means that
drivers must be aware that this field applies to all HT
traffic for this virtual interface, not just the traffic
within the BSS. Document that.

For people who only need binary kernel package, there is now bindeb-pkg
target, same target also used to build the .deb files if built from the
source package using dpkg-buildpackage.

Generated source package will build the same kernel .config than what
was available for make deb-pkg. The name of the source package can
be set with KDEB_SOURCENAME enviroment variable.

The source package is useful for GPL compliance, or for feeding to a
automated debian package builder.

21adf76e90 perf/urgent fixes:
- In some cases where perf_event.fork.{pid,tid} should be used we were instead
   using perf_event.comm.{pid,tid}, which is not a problem for for the 'pid'
   case, that sits in the same place in these union_perf_event members, but
   comm.tid sits where fork.ppid is, oops.
 
   These cases were considered as (potentially) problematic:
 
    - 'perf script' with !sample_id_all, i.e. only non old kernels without
       perf_event_attr.sample_id_all.
 
    - intel_pt could be affected when decoding without timestamps, as the exit
      event is only used to flush out data which anyway gets flushed at the
      end of the session.
 
    - intel_bts also uses the exit event to flush data which would probably not
      cause errors as it would get flushed at the end of the session instead.
 
   Fix it. (Adrian Hunter)
 
 - Due to relaxing the compiler checks for bison generated files, we missed
   updating one parse_events_add_pmu() caller when this function had its
   prototype changed, fix it. (Jiri Olsa)

  - In some cases where perf_event.fork.{pid,tid} should be used we were instead
    using perf_event.comm.{pid,tid}, which is not a problem for for the 'pid'
    case, that sits in the same place in these union_perf_event members, but
    comm.tid sits where fork.ppid is, oops.

    These cases were considered as (potentially) problematic:

     - 'perf script' with !sample_id_all, i.e. only non old kernels without
        perf_event_attr.sample_id_all.

     - intel_pt could be affected when decoding without timestamps, as the exit
       event is only used to flush out data which anyway gets flushed at the
       end of the session.

     - intel_bts also uses the exit event to flush data which would probably not
       cause errors as it would get flushed at the end of the session instead.

    Fix it. (Adrian Hunter)

  - Due to relaxing the compiler checks for bison generated files, we missed
    updating one parse_events_add_pmu() caller when this function had its
    prototype changed, fix it. (Jiri Olsa)

96d12cbdbd drm/i915: access the PP_ON_DELAYS/PP_OFF_DELAYS regs only pre GEN5
These registers exist only before GEN5, so currently we may access
undefined registers on VLV/CHV and BXT. Apply the workaround only pre
GEN5.

Since the workaround is relevant only when LVDS is present, for clarity
apply it only if this is the case.

This triggered an unclaimed register access warning on BXT.

v2: (Ville)
- move the workaround to the LVDS init code
- print a debug note about the workaround

1da7d7131c drm/i915: ignore link rate in TPS3 selection
TPS3 is mandatory for downstream devices that support HBR2, and Intel
platforms that support HBR2 also support TPS3. Whenever TPS3 is
supported by both the source and sink, it should be used. In other
words, whenever the source and sink are capable of 5.4 Gbps link, we
should anyway go for TPS3, regardless of the link rate being selected.

Log an error if the sink has advertized HBR2 capability without TPS3
capability.

3a41a05d70 drm/i915/gtt: Avoid calling kcalloc in a loop when allocating temp bitmaps
On each call to gen8_alloc_va_range_3lvl we're allocating temporary
bitmaps needed for error handling. Unfortunately, when we increase
address space size (48b ppgtt) we do additional (512 - 4) calls to
kcalloc, increasing latency between exec and actual start of execution
on the GPU. Let's just do a single kcalloc, we can also drop the size
from free_gen8_temp_bitmaps since it's no longer used.

v2: Use GFP_TEMPORARY to make the allocations reclaimable.
v3: Drop the 2D array, just allocate a single block.
v4: Rebase to handle gen8_preallocate_top_level_pdps.
v5: Align misaligned bracket.

93efac3f2e ipv6: Fix IPsec pre-encap fragmentation check
The IPv6 IPsec pre-encap path performs fragmentation for tunnel-mode
packets.  That is, we perform fragmentation pre-encap rather than
post-encap.

A check was added later to ensure that proper MTU information is
passed back for locally generated traffic.  Unfortunately this
check was performed on all IPsec packets, including transport-mode
packets.

What's more, the check failed to take GSO into account.

The end result is that transport-mode GSO packets get dropped at
the check.

This patch fixes it by moving the tunnel mode check forward as well
as adding the GSO check.

eb38f3a4f6 Input: evdev - do not report errors form flush()
We've got bug reports showing the old systemd-logind (at least
system-210) aborting unexpectedly, and this turned out to be because
of an invalid error code from close() call to evdev devices.  close()
is supposed to return only either EINTR or EBADFD, while the device
returned ENODEV.  logind was overreacting to it and decided to kill
itself when an unexpected error code was received.  What a tragedy.

The bad error code comes from flush fops, and actually evdev_flush()
returns ENODEV when device is disconnected or client's access to it is
revoked. But in these cases the fact that flush did not actually happen is
not an error, but rather normal behavior. For non-disconnected devices
result of flush is also not that interesting as there is no potential of
data loss and even if it fails application has no way of handling the
error. Because of that we are better off always returning success from
evdev_flush().

Also returning EINTR from flush()/close() is discouraged (as it is not
clear how application should handle this error), so let's stop taking
evdev->mutex interruptibly.

 "This is the main pull request for 4.3 for MIPS.  Here's the summary:

  Three fixes that didn't make 4.2-stable:

   - a -Os build might compile the kernel using the MIPS16 instruction
     set but the R2 optimized inline functions in <uapi/asm/swab.h> are
     implemented using 32-bit wide instructions which is invalid.

   - a build error in pgtable-bits.h for a particular kernel
     configuration.

   - accessing registers of the CM GCR might have been compiled to use
     64 bit accesses but these registers are onl 32 bit wide.

  And also a few new bits:

   - move the ATH79 GPIO driver to drivers/gpio

   - the definition of IRQCHIP_DECLARE has moved to linux/irqchip.h,
     change ATH79 accordingly.

   - fix definition of pgprot_writecombine

   - add an implementation of dma_map_ops.mmap

   - fix alignment of quiet build output for vmlinuz link

   - BCM47xx: Use kmemdup rather than duplicating its implementation

   - Netlogic: Fix 0x0x prefixes of constants.

   - merge Bjorn Helgaas' series to remove most of the weak keywords
     from function declarations.

   - CP0 and CP1 registers are best considered treated as unsigned
     values to avoid large values from becoming negative values.

   - improve support for the MIPS GIC timer.

   - enable common clock framework for Malta and SEAD3.

   - a number of improvments and fixes to dump_tlb().

   - document the MIPS TLB dump functionality in Magic SysRq.

   - Cavium Octeon CN68XX improvments.

   - NetLogic improvments.

   - irq: Use access helper irq_data_get_affinity_mask.

   - handle MSA unaligned accesses.

   - a number of R6-related math-emu fixes.

   - support for I6400.

   - improvments to MSA support.

   - add uprobes support.

   - move from deprecated __initcall to arch_initcall.

   - remove finish_arch_switch().

   - IRQ cleanups by Thomas Gleixner.

   - migrate to new 'set-state' interface.

   - random small cleanups"
